Exposure Control

The amount of light reaching the film plane is deter

mined by a combination of the lens aperture and the

shutter speed. Since the two are interrelated, different

combinations will give the same exposure. A 1-step

change in the shutter speed, or a 1-stop change in the

aperture setting, will either halve or double the exposure.

For example, a shutter speed of 1/125 second passes

twice as much light as a setting of 1/250 second, and

only half as much light as a speed of 1/60 second; for an

aperture setting of f/11, twice as much light as f/16, and

half as much as f/8, is passed. This feature characterizes

the operation throughout the available range of shutter

speeds and aperture settings. With this in mind, it’s easy

to see that if a correct exposure for a scene is 1 /125 at

f/11, then 1 /60 at f/16 or 1 /250 at f/8 will be equally

acceptable.

The best combination for your needs will depend on the

results desired. Use fast shutter speeds to freeze motion,

or use slow speeds to produce deliberate and creative

blur. Small apertures give greater depth of field, while

large apertures restrict sharp focus to the main subject.

The creative selection of both speeds and apertures will

greatly enhance your photography.
